We're dividing 65236019 by 345 
The aim is to understand the frequency of 345 in 65236019.

Going ahead to step 1:
345 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 345

Going ahead to step 2:
If we divide 65 by 345, we get 0 and a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Bring next digit (2) of the dividend behind the 65 and repeat the process: 652 / 345

Moving on to step 3:
345 goes into 652 1 times with a remainder of 307.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 345 from 652 to get 307.
Grab the next digit (3) from the dividend, add it to 307, then carry on: 3073 / 345

Moving on to step 4:
345 can be fit into 3073 8 times, resulting in a remainder of 313.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 2760 from 3073 leaves us with 313.
Take the next digit (6) from the dividend and append it to 313, then repeat: 3136 / 345

Going ahead to step 5:
When dividing 3136 by 345, we get 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 189.0
Subtract 3105 from 3136 to get 31.
Include the next digit (0) from the dividend after 31, then repeat: 310 / 345

On to step 6:
The number 345 fits into 310 0 times, leaving a remainder of 310.
Write down 0 as next digit of the result. 
Result so far: 1890.0
Subtract 0 from 310 to get 310.
Include the next digit (1) from the dividend after 310, then repeat: 3101 / 345

Step 7:
345 can be fit into 3101 8 times, resulting in a remainder of 341.
The number 8 becomes the next digit in our result. 
Result so far: 18908.0
Subtracting 2760 from 3101 leaves us with 341.
Take the next digit (9) from the dividend and append it to 341, then repeat: 3419 / 345

Advancing to step 8:
The number 345 fits into 3419 9 times, leaving a remainder of 314.
Write down 9 as next digit of the result. 
Result so far: 189089.0
If we subtract 3105 from 3419, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

On to step 9:
If we divide 3140 by 345, we get 9 and a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 189089.9
The remainder is 35 after subtracting 3105 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
When dividing 350 by 345, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 189089.91
Subtract 345 from 350 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
345 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 189089.91
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
The number 345 fits into 500 1 times, leaving a remainder of 155.
Put 1 as the next digit of the answer. 
Result so far: 189089.9101
Subtracting 345 from 500 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 13:
345 can be fit into 1550 4 times, resulting in a remainder of 170.
The number 4 becomes the next digit in our result. 
Result so far: 189089.91014
If we subtract 1380 from 1550, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 14:
345 goes into 1700 4 times with a remainder of 320.
Record the quotient 4 as the next digit in the result. 
Result so far: 189089.910144
If we subtract 1380 from 1700, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Our division results in 189089.910144 with a remaining 3.2e-05.
